4 | Subject: [PATCH] check for sys/pidfd.h | ||
5 | |||
6 | This header in newer glibc defines the signatures of functions | ||
7 | pidfd_send_signal() and pidfd_open() and when these functions are | ||
8 | defined by libc then we need to include the relevant header to get | ||
9 | the definitions. Clang 15+ has started to error out when function | ||
10 | signatures are missing. | ||
11 | |||
12 | Fixes errors like | ||
13 | misc-utils/kill.c:402:6: error: call to undeclared function 'pidfd_send_signal'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] | ||
14 | if (pidfd_send_signal(pfd, ctl->numsig, &info, 0) < 0) | ||
